The 3.5mm fixed line level output can pass the signal on to an additional amplifier, such as a Head Box S2. A 12V trigger output can remotely turn on other products with trigger input for improved comfort and convenience. The incredibly low harmonic distortion levels guarantee a listening experience which has never been available in this pricerange! The housing is made of an aluminium/metal sandwich construction for highest aesthetics and to protect against unwanted electromagnetic interference and vibratios. Pre Box S2 Analogue comes in silver or black and can be powered by any 5V powerbank or the supplied power supply.
